Question

Help needed related python task ! Thanx again

How you're doing it
• Write a function write_to_file() that accepts a tuple to be added to the end of a file
o Open the file for appending (name your file 'student_info.txt')
o Write the tuple on one line (include any newline characters necessary)
o Close the file
• Write a function get_student_info() that
o Accepts an argument for a student name
o Prompts the user to input as many test scores as they wish
o Stores the information (name and scores) in a tuple
o Calls the function write_to_file() sending the tuple to be written to the end of the file
• Write a function read_from_file() that
o Reads a file line by line
o Prints each line to the console
• In main
o Call the get_student_info() for at least 4 different students.
o Call read_from_file()
Notes/Hints
• Because tuples are immutable, you'll want to store your data in a tuple that has a list nested inside of it.
o ('name',[score1,score2,score3,etc.])
o You'll be able to edit the list inside the tuple. In the example above, you could append to the list by doing something like this: score_list[1].append(student_score)
• There are more elegent ways to do things but for this assignment, you can just write the tuples to the file as strings and then read the strings back at the end of the program
• Remember that you'll also need to include a "\n" to each line you write to the file so you don't just end up with one long string on a single line
• Because you are going to be appending to the file each time, it might be good for you to include this as the first thing you do in your main:
o open("student_info.txt","w").close()
o It basically overwrites the file with a blank file.
o This prevents you from appending more and more each time you rerun your program.

Answer 1

Here there are many ways to solve depending upon the platform like jupyter notebook but i will do simply so lets go for it

def write_to_file(tuple)

f= open("student_info.txt","w") // opening the file

f.write("My name is "+ myname + " \n") // Appending the file

f.close()

def get_student_info():

st=list()

n=int(input('Enter the number of the student :'))

print('Students entry')

for i in range(n):

print('Student :',i+1)

rollno=input('\tRollnumber:')

name=input(\tname:')

age=int(input(\tage:')

st.append(Student(rollno,name,age)

print("Student Information")

print("rollno\t\tname\t\tage")

for i in range(n):

for j in range (i+1,n):

if(st[i].name>st[j].name):

tmp=st[i]

st[i]=st[j]

st[j]=tmp

Program Files:

StudentScores.py

"""
   Python program to read and store student details in a text file
"""

# declaring filename
filename = 'student_info.txt'

def write_to_file(studentTuple):
"""
write the given tuplet to the txt file
"""

# open file to append data
writeFile = open(filename, 'a')

# writing the tuple with a new line character
writeFile.write(studentTuple)
writeFile.write("\n")

# close the file
writeFile.close()

def get_student_info(studentName):
"""
Accepts an argument for a student name
Prompts the user to input as many test scores as they wish
Stores the information (name and scores) in a tuple
"""

# list to store the scores
scores = []

print("Enter Scores for", studentName)

while(True):

score = int(input("Enter score : "))
scores.append(score)

# prompt to user for continue
userChoice = input("Do you want to add more scores (y/n) : ")

# if the user dont want to continue break the while loop
if(userChoice.lower() != "y"):
break

# write the tuplet the text file
write_to_file(str((studentName, scores)))

def read_from_file():

main()

student_info.txt

('student1', [23, 45, 55])

output:
